Abstract

The invention relates to the technical field of mining, in particular to a double-layered and bidirectional horizontal stripping open-stope backfilling mining method. The double-layered and bidirectional horizontal stripping open-stope backfilling mining method comprises the following steps: S7, separately forming two lower slice slicing stope openings in two sides of the tail of a vein connectionroadway, separately arranging lower slice stope connection roadways towards an lower slice stope of a stope in step one and an lower slice stope of a stope in step two from every lower slice stope; S8, continuing tunneling and arranging upper and lower slice connection roadways in the extension direction of the vein connection roadway from the tail of the vein connection roadway, and enabling thetails of the higher and lower slice connection roadways to be positioned between the two higher slice stopes of an adjacent horizontal stope below a horizontal stope in step S6; and S9, separately forming two upper slice stope openings in the two sides of the openings of the upper and lower slice connection roadways, separately arranging upper slice stope connection roadways towards an upper slice stope of the stope in step one and an upper slice stope of the stope in step two from every upper slice stope opening, and enabling the opening of each upper slice stope connection roadway to be positioned in the center of the corresponding upper slice stope.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a double-layer bidirectional horizontal slitting open field subsequent filling mining method. Background technique [0002] With the continuous mining of metal mines, the level of mine mechanization has also developed rapidly. However, due to the different occurrences of ore bodies, the level of mining mechanization is also different. Among them, the gently inclined ore bodies greater than 15° are ore bodies that are difficult to achieve mechanized mining. Due to the limited climbing ability of mining equipment, and the degree of mechanization is often the same as The mining and cutting ratio is proportional, so there are still many problems in the mechanized mining of this type of ore body. At present, the mining methods for mining this type of ore body mainly include the room-and-pillar method, the strip caving method, the upward horizontal layered filling mining method, and th...
